S7007 CD/P4ADGA Bearing Product Overview & Core Advantages
The S7007 CD/P4ADGA is a premium double row angular contact ball bearing designed for applications demanding exceptional precision and rigidity. Engineered to accommodate combined loads (radial and bidirectional axial loads) simultaneously, this bearing features a compact design ideal for space-constrained, high-performance machinery. Its P4A tolerance class ensures superior running accuracy, while the sealed construction and pre-lubrication offer reliable, long-term operation with minimal maintenance. This bearing is the optimal choice for spindles and other precision applications requiring high speed, high rigidity, and outstanding operational reliability.

S7007 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior radial and axial stiffness, enabling stable support under combined loads. With a dynamic load rating of 5738 lbf and static load rating of 4275 lbf, it handles significant operational stresses.
- Optimized High-Speed Performance: The phenolic cage and 15° contact angle are engineered for minimal centrifugal forces and friction, contributing to a high limiting speed of 41,000 rpm. This makes it an ideal high-speed bearing for precision spindles.
- Sealed & Pre-Lubricated for Longevity: As a sealed bearing pre-filled with grease, it is protected from contamination and offers a wide operating temperature range (-30°C to 110°C). This design ensures long service life with minimal maintenance requirements.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls on bore, outside diameter, and width, this bearing guarantees exceptional running accuracy and reduced vibration in sensitive applications.
